Product Details

The ADP7102 is a CMOS, low dropout linear regulator that operates from 3.3 V to 20 V and provides up to 300 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 19 V to 1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1 μF ceramic output capacitor.

The ADP7102 is available in 7 fixed output voltage options and an adjustable version, which allows output voltages that range from 1.22 V to VIN − VDO via an external feedback divider.

The ADP7102 output noise voltage is 15 μV rms and is independent of the output voltage. A digital power good output allows power system monitors to check the health of the output voltage. A user programmable precision undervoltage lockout function facilitates sequencing of multiple power supplies.

The ADP7102 is available in 8-lead, 3 mm × 3 mm LFCSP and 8-lead SOIC packages. The LFCSP offers a very compact solution and also provides excellent thermal performance for applications requiring up to 300 mA of output current in a small, low-profile footprint.

Evaluation Kits

Product Details

This product has individual evaluations boards at specific voltages or with specific features as well as the RedyKit™. The RedyKit simplifies product evaluation by providing two assembled and tested evaluation boards, plus a full set of product (voltage) options for an IC regulator. All the IC options come sorted and stored in the kit with the Analog Devices part number clearly printed on each antistatic zip-top bag.

Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.

Product Details

In order to get the correct unpopulated evaluation board with an appropriate Bill of Materials and Schematic, you need to use the button for "Request Evaluation Board" from within the design tool. Make sure the design tool is in a state that matches your desired power requirements.

This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.

Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.

Tools & Simulations

Design Tools

This expert design tool produces custom DC-DC converter designs in about a minute. The user enters 5 inputs and chooses to optimize for efficiency, PCB space, cost, or part count. Output is a complete schematic, BOM, efficiency plot, and performance summary. A PDF summary and a blank PCB is offered for each design to facilitate fast prototyping to verify the design.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.

We used ADM7150 and ADP7102 for the power supply of operational amplifier in PLL，and we fund that the higher noise using the two chips comparied with Agilent's phase noise analyzer.
ADM7150 and ADP7102 needed grouding when they were welded on PCB board。Because the hole of PCB board that we design is little,the welding of the two chips is very hard. Finally，we use a very thin copper wire under the ADM7150 or ADP7102 to connect ground.So we do not know whether this grounding method lead to the higher noise.
